The apartment was very nice, spacious, clean and certainly very very safe & secure.
The location puts you in "real Bangkok" - don't expect to walk out the door and be in "tourist central", but if you really want to experience how the locals live, this is perfect.
The only downside is that it is a little tricky for taxi drivers to find, but we overcame that very easily in two ways... firstly, Michelle is extremely helpful - on the night we arrived, we didn't get in until nearly 11pm, but she waited up and answered the phone call so I could get her to explain to the taxi driver how to get there; secondly, Michelle provides a page with explanation about transport options which made it very easy for us.
Overall we were very happy with our stay.
